“…9 and 10). It seems that this kind of behaviour can be explained on the basis of some earlier studies [33]. It has been stated, that during the lithium deintercalation at the voltage of 4 V, phospho-olivine phases with different lithium concentrations are formed.…”

“…9 Finally, the electrochemical properties of manganese phosphates are now proving to be of industrial interest. 10,11 Although manganese phosphates are among the most widespread of all mineral phosphates, the synthetic compounds with an open framework are very scarce and the chemistry of new phases in this area is emerging. The majority of the reported phases contain only Mn 2+ , 12,13 and open structures with Mn 3+ are rare.…”

A new template-free layered manganese(III) phosphate, Na 3 MnH(P 0.9 O 4 ) 2 , has been hydrothermally synthesized. The crystal structure was solved ab initio from powder X-ray diffraction data, and the model was confirmed using the Rietveld method. The material crystallizes in triclinic space group P1 j (No. 2) with lattice parameters a ) 5.2925(2) Å, b ) 6.9004(3) Å, c ) 5.2452(3) Å, R ) 91.56(0)°, β ) 116.95(0)°, γ ) 90.5(0)°, and Z ) 1. The structure consists of [Mn(P 0.9 O 4 ) 2 ] ∞ layers composed of isolated MnO 6 octahedra connected via corner-sharing asymmetric PO 4 tetrahedra. The interconnection between the layers is assured by Na + cations, which reside in the interlayered space. The system is paramagnetic above 50 K, with an effective paramagnetic moment of 4.85(3) µ B , ascertaining the Mn 3+ valence state of the Mn ions. Antiferromagnetic short-range-order effects are observed below 26.5 K.
